Harman Kardon Onyx StudioIf you want something powerful enough to actually warrant noise complaints, look no further. First on the outdoor-party-capable Bluetooth speaker list is the Harman Kardon Onyx Studio. This UFO-shaped speaker packs a serious punch, and its an absolute steal right now on Amazon where you can pick it up for under $150. The only downside to the Onyx is its battery life - with 2600mAh of reserve power, the Onyx will need a refill after about 4 hours.

JBL XtremeThis speaker is basically the JBL Charge or Pulse’s big brother, and its honestly the best thing we’ve ever heard for its size. It’s so loud, and the bass bumps so hard that people rarely even believe that the sound is coming from this thing when we turned it on in public. And battery life isn’t a concern either - with a massive 10,000 mAh battery onboard you can keep the party going for up to 15 hours between charges. But since you probably won’t need all of that, you can also use it to charge your phone in the meantime with the 2 USB ports in the back. Best of all, its still small enough to fit comfortably in a backpack. It’s a bit pricy at $299, but honestly, for us, its definitely worth the price.

Aiwa Exos-9If you wanted something even louder, for reasons we can’t even really guess at, there’s one last option. Since its basically just a giant modern boombox with Bluetooth support, the Exos certainly isn’t very portable, but holy crap is it loud. It also comes with its own built in Equalizer knob, so you can tweak the sound and get it just right. The Aiwa also costs $299.
